Bad Service Repeatedly

It has been 2 months now that I have no internet and wifi connections available at my home. I have called and spoke to several call centre agents, each with their own level of arrogance. I have reference numbers provided time and time again for a new fault to be lodged when the existing fault has never been fixed. Team leaders and Supervisors never call back, when I request to speak to them, they're either on a tea break, lunch or on another call. no one ever calls me back. Technicians come to my place, fiddle to whatever and then advise Telkom that the case is closed. Closed, my ass, how can the case be closed when the issue is still remaining and still left without any connection. Don't know who else to contact to resolve my issue.
